Hey guys I am installing my jumper harness. I am in the BCM and I cant find the correct wires for the turn signals. There is not a blue wire to splice into for the left signal and there is not even a wire in the spot where the right signal is suppose to plug into and splice. Any help would be greatly appreciated. This is on a 2014 GMC sierra 1500 crew cab 4x4. Thank you in advance. if someone has a BCM wiring diagram that would help also.

I believe you posted this message on my YouTube video of the install? If so, I haven't forgotten about you. :). Been tied up with work all day today. Let me look into this.. but generally speaking, if you are 2014... you might not have the wires present in the BCM to splice into and that's what the RZY accomplishes.

 

The blue/green turn Signal wires that have terminals on them with the butt splices next to them...the butt splices are used IF there is a wire present in the BCM. Essentially, you remove the existing terminal, cut the terminal off, strip and splice that into the butt splice. Then insert the new wire with the terminal back into that slot.

 

So - if you don't have the blue/green wires present in the BCM, you should just need to insert the blue/green wires in their spot... the butt splices are omitted.

 

Hope this helps.

Yes I did post that on your video. Thank you for getting back to me. I was thinking that may be the case, but wanted to check first. I appreciate the fact you will look into it for me. My only concern is the left turn signal. There is a wire in the spot , but it is not the correct color. I believe it may be brown. I am at work now and have given up for the night. One last thing the 41 pins did have pins in them. That is why I am confused.Thanks again

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ).    I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.
